You might want to back them up that way once a month or when you have a maintenance window so that you have a full backup of the image files. Then do your incrementals via netbackup in the guest domains. So for DR, you would restore the full image files, startup the guest domains, and restore the rest of the data. If you were using ZFS, you could use snapshots/clones as well. *-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-* Octave J.

Since my Guest Domains have as Backend a VxVM Volume/VxFS filesystem Mounted on /fs1 for example what I need to backup (we are using Veritas NetBackup enterprise software) from the Guest Domain point of view ? Do I need to do a backup of my entire /fs1 filesystem where resides the O.S. Solaris 10 image of my Guest Domain? 2) When I have to restore my Guest Domain do I need only to restore That specific filesystem /fs1 ? Please any help/suggestion/ideas will be great. Thanks.

Archive and backup the guest domain configuration: # ldm list-constraints -x <ldom> > <ldom>.xml 2. Backup the guest domains over the network by installing the netbackup client inside the guest domain. Add it to your backup sched and backup as you would a normal server. For full guest domain recovery, the key things are: 1. Restore the guest domain configuration if it has been lost. This assumes that your VSW and VDS resources are available: # ldm add-domain -i <ldom>.xml 2. Make sure that you have enough VCPU, MAU, and Memory to boot your guest domain. 3. Jumpstart guest domain 4. Install netbackup client 5. Do netbackup restore. For the primary domain backup: 1. Backup the LDM db files in: /var/opt/SUNWldm 2. Archive and backup the primary domain configuration: # ldm list-constraints -x primary > primary.xml 3. Backup the primary domain over the network by installing the netbackup client, setup sched and backup as normal. For full primary domain recovery: 1. Update firmware 2. Install netbackup client 3. Install LDM software 4. Restore /var/opt/SUNWldm 5. Start up LDM services 6. If all goes well, the LDM config will be read and you will be in initial configuration mode. Save the config to the hypervisor and reboot. If not, parse the primary.xml file to recreate the primary domain configuration, save config, and reboot. 7. Restore guest domain configs and data. Then bring up guest domains. I hope that helps. *-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-* Octave J.
